SIMATIC S7-400 · INDUSTRIAL ETHERNET
CP 443-1 Advanced Communications Processor
Siemens 6GK7443-1GX30-0XE0 is the CP 443-1 Advanced communications processor for connecting a SIMATIC S7-400 automation system to Industrial Ethernet. Its network architecture combines a gigabit Ethernet connection with a separate four-port switch interface for PROFINET communication. The module supports controller-level data exchange, distributed I/O integration and engineering access within a configured automation network. For replacement planning, identify the installed CPU, rack configuration, hardware revision and firmware before selecting the spare. Stockoems supplies the requested part with commercial condition and warranty details, while compatibility remains dependent on the complete installation and project configuration.
Condition, availability and warranty are Stockoems commercial information, not manufacturer commitments. Siemens lists product phase-out starting on 1 October 2026.
Provides the gigabit-capable Ethernet connection. Define addressing, routing and permitted communication paths as part of the plant network design.
Connects the configured PROFINET network. Cyclic I/O uses 100 Mbps full duplex; validate the topology and device configuration during commissioning.
S7 communication and open SEND/RECEIVE services support automation data exchange. Routing and web diagnostics assist network integration and maintenance; their use must follow the approved project and security configuration.
Connecting a configured PROFINET I/O network to an S7-400 automation system.
Supporting communication between an S7-400 installation and configured Ethernet communication partners.
Restoring an existing communication path using a revision-checked spare and the approved engineering project.
Use the complete part number together with product label photos, the installed CPU and rack details, hardware revision, firmware and engineering software version. Identical connector appearance does not establish interchangeability. Back up the project and record network addressing before replacement. Review current Siemens firmware and security notices, apply appropriate network segmentation and have qualified personnel verify the installation before return to service.
It is a CP 443-1 Advanced communications processor for S7-400 systems, not a standalone PLC CPU. Select it against the communication requirements of the installed automation system.
No. One connection supports 10/100/1000 Mbps. The separate four-port switch supports 10/100 Mbps. Check the intended network segment before assigning cables.
Yes. It supports the PROFINET IO controller role. Cyclic PROFINET IO operation requires 100 Mbps full-duplex communication and a compatible engineering configuration.
Match the full order number, hardware revision, firmware, CPU compatibility and engineering software. Review the existing IP addressing, port assignments and project backup before changing the installation.
The Siemens catalog identifies the product as Active and lists product phase-out starting on 1 October 2026. A phase-out start date is not the same as a declaration that the product is already discontinued.
Stockoems offers this item as Original new, In stock and With 1 year warranty. These are Stockoems commercial terms; the written quotation and warranty terms define the scope.
Send us the complete part number, required quantity, destination country and product label photos. Our team will check availability, condition, compatibility requirements and shipping options.

A coordinated procurement review for Siemens 6GK7443-1GX30-0XE0, from model verification to shipment follow-up.
Stockoems coordinates product identification, photo requests, packing instructions, logistics questions and document preparation through the same sales contact. This keeps purchasing and engineering requirements together and gives your team a consistent channel for after-sales communication.
Look for a verifiable business identity, clear contact details, item-specific photos and written condition and warranty terms. A supplier should distinguish stock claims from manufacturer technical data and explain the inspection scope without implying manufacturer authorization.
Match the full model and suffix across the quotation, product label and purchase order. Record quantity, condition, shipment destination, packaging requirements, commercial terms and the documents required for customs clearance.
Request readable label and connector photos, hardware revision and firmware information where available. Compare these with the installed S7-400 configuration and the approved project; a matching front panel alone does not prove compatibility.
Treat inconsistent suffixes, reused or unreadable label photos, unexplained substitutions, unverifiable stock quantities and refusal to provide written terms as warning signs. A request to skip compatibility review should prompt further checks.
Stockoems provides written warranty terms for the quoted item. Report the order number, installation context and observed issue through the contact channels below. Obtain return authorization before shipment so handling and assessment can be coordinated.
Send the complete part number, quantity and destination together with the product label photos and any installation requirements.
